Description

Technology for producing paper-face plaster board and special equipment thereof

The present invention relates to a kind of dividing plate of building, specifically a kind of production method of Thistle board.

Thistle board is a kind of dividing plate for building, and its production equipment is the Large Scale and Continuous automatic production line of external import.On this production line, after land plaster, cellulose and water mix in proportion,,, cut after the drying more then through being extruded to shape through stirring on the continuous running workbench that injects the automatic shop of band paper function, make the specification finished product.This automatic degree of production line height, output is big, can produce Thistle board continuously in large quantity.Its weak point is that equipment is many, and floor space is big, and investment surpasses 10,000,000 RMB, makes the corresponding raising of product cost, average every square metre of 8-10 unit.Again because of equipment precision height, to the corresponding raising that requires of raw material, to reach about the 1000-1200 order as the fineness of land plaster, reduce as fineness, then the property of product is crisp, easy fracture.In addition because of being continuous production, spreading paper continuously, if any the bias phenomenon of shop paper (＞2mm), then can cause the scrapping of product of whole volume shop paper length, form huge waste.Having is that the output of this main equipment is very high again, uses in a city, often is difficult to digestion; And use in the strange land, then has the problem of cost of transportation and breakage rate to exist.

Purpose of the present invention just provides a kind of production technology and matching special equipment thereof of miniaturization production of Thistle board, and to reduce equipment investment and production cost, make it to be adapted at each city and go into operation, thus problems such as solution transportation.

The present invention is achieved in that and send the mixer stirring with raw material, at special molding machine upper berth base stock, stand material, roll-forming, repaves facial tissue roll-in typing again, Thistle board is placed on to deliver on the carriage cuts edge after drying kiln is dried, and makes finished product.Raw material in this production technology still is land plaster, cellulose and water etc., and mixed proportion remains unchanged, the key point of its invention is artificial participating in, make each operations such as cutting a sheet of paper, spread paper, stand material, roll-in and side cut by artificial realization, this just makes the production equipment in this technology only keep essential equipment such as kneading mill, make-up machine, carriage and drying kiln, thereby make equipment investment drop to tens0000 yuan by ten million yuan, adapt in the Chinese national conditions and the investment capacity.

Shaping equipment of the present invention is achieved in that this make-up machine has a rectangular table, there is contour convex edge on table top two long limits at workbench, middle part, side at workbench two minor faces is connected with gripper shoe with bolt, rotating shaft is arranged on the gripper shoe, be fixed on the bearing block behind the outer end socket bearing of rotating shaft, bearing block is fixed on the support, one end has gripper shoe with bolting in the short side of workbench, pole is arranged on the gripper shoe, be provided with H type carriage on the support of corresponding pole position, latch is equipped with on carriage two vertical rod tops.When raw material spreads out after on the table surface, with the format roll frame on two convex edges, back and forth roll-in, the raw material natural coagulation can become plasterboard.The base stock of plate face both sides and facial tissue are in roll-in, because the adhesivity in the raw material makes it to adhere to automatically on the plate face.This former is a key equipment of realizing production technology of the present invention, and its molding mode is simple, and is easy to operate, and the especially design of working platform overturning form is particularly suitable for the characteristic of Thistle board, makes it quick to the convenient transfer of carriage.This is because the make-up machine table surface is very bright and clean smooth, the stand material roller is molded behind the shop fixtures paper, repave facial tissue roll-in typing, because raw material has certain viscosity, can bonding voluntarily paper, and got rid of interstitial air between moistening base stock and the workbench after roll-in, it is certain moist right with vacuum-junction that Thistle board and table top are had, and can not come off voluntarily when having guaranteed upset.And after upset, as long as in panel edges along slightly prizing a crack, can make to fall within on the carriage under the entire paper surface gypsum board, realize separating of plasterboard and table top.

Below in conjunction with drawings and Examples the present invention is further described.

Fig. 1, Fig. 2 are the structural representations of shaping equipment of the present invention.

Production technology of the present invention is 300-400 purpose land plaster and cellulose and water to be packed into to stir in the kneading mill earlier.Mixer can be selected commercially available lift mixer for use, and mixing time got final product at 3-5 minute.Time is too short can to influence the raw material mixture homogeneity, longly then can influence production efficiency.The base stock that to cut out in advance is layered on the make-up machine workbench then, batch mixing is poured on the table top, with format roll roll-in one time again, make the plasterboard moulding, repave facial tissue, roll-in is one time again, facial tissue was attached on the plasterboard, can have made plasterboard further plain again.The workbench that overturns then makes Thistle board downward, pushes carriage again, prizes plasterboard from mesa edge, and then whole plate can fall within on the carriage, send the drying kiln oven dry.Drying kiln can adopt tunnel type, and from the middle part hot wind supply, the two ends air-out makes carriage process from entering out in kiln, realizes preheating, the drying procedure of drying, bringing down a fever, and helps the high-quality drying of Thistle board like this.Bake out temperature is at 160-180 ℃, and drying time was at 6-8 hour.If temperature is crossed low or the time short, then drying effect is undesirable, and the baking that promptly is commonly called as is not done; If temperature is too high or overlong time, the alice distortion situation of Thistle board then can appear, cause waste product.Suitable technological parameter screening also is one of key point of the present invention.

Former of the present invention has a cast iron rectangular table 1 as shown in drawings, and respectively there is a convex edge 2 at the edge, two long limits of table surface.Article two, the convex edge is parallel, contour, and it highly is the thickness of Thistle board.Distance between the length of workbench and two convex edges is the length and width specification of plasterboard.The specification difference, then workbench can be made into corresponding series.Middle part, side at two minor faces of workbench is connected with gripper shoe 3 with bolt, is welded with rotating shaft 4 on the gripper shoe, is fixed on the bearing block 5 behind the outer end socket bearing of rotating shaft 4.Bearing block is fixed by bolts on the support 6, and support is " door " shape frame with angle steel welding, and two perpendicular legs are fixed on the ground, and it highly should be greater than half of workbench bond length, so that working platform overturning.One end has gripper shoe 7 with bolting in the side of workbench minor face, is welded with pole 8 on the gripper shoe 7, and pole 8 is parallel with the axis of rotating shaft 4.Be welded with H type carriage 9 on the support 6 of corresponding pole position, latch 10 is equipped with on two vertical rod tops of carriage 9.When workbench 1 during in the normal position, 8 of the poles on both sides are on carriage 9, and by latch 10 locking branch, in case workbench overturns voluntarily.When need upset workbench, extract latch 10 out, handle pole 8, promptly turning workbench.Because the rotating shaft of workbench is on centre symmetry line, so its upset is very light, dexterous.In addition, but on the pole 8 of workbench side one section sebific duct 11 of socket also so that 9 one-tenth Elastic Contact of pole and H type carriage are alleviated impulsive force, prolong service life of equipment.

As shown in Figure 1, also can weld an oblique carriage 12 that is placed to forming roll in the outside of support 6, promptly after format roll 13 leaves table surface, can be placed on the carriage, and not need to be put on the ground again.So both can alleviate labor strength, and can protect the outer surface of format roll not pressed against wound again simultaneously, to keep roll-in plane effect preferably.Format roll 13 can be made with steel pipe, at both ends welding outrigger shaft, operates and when moving format roll, all carries out on this axle.

The present invention is miniaturization technology for producing paper-face plaster board and equipment, and equipment investment is below 200,000 yuan, and floor space is little, being adapted at various places goes into operation, because of production scale is not high, can solve transportation and damaging problem that the strange land produces thus again fully an area digestion.This production technology manually to participate in composition many, equipment precision is low, thereby to the corresponding reduction of raw material required precision, surpasses over halfly as the reduction of land plaster fineness, and after testing, product performance index still can reach the GB requirement.In addition, because of being individual production, also only be individual if any waste product, can not influence each other, percent defective is decreased.Production technology of the present invention and equipment are all very simple, and small investment, and cost of material is low, and percent defective is low, and it is minimum that these all make the cost of the product of producing reduce to, and reach every square metre below 6 yuan, and its market competitiveness obviously improves.
